Rotate them to the back and test again. 2) Brake Rotors – Your brake rotors may be warped, any rotor that has more than .003 run-out is warped and should be turned or replaced. 3) Wheel Bearings – Your wheel bearing may be loose or damaged and may need to be adjusted accordingly. The above is based on a 2WD truck, if it is 4WD you may need to jack up the front end and check your ball joints as well as the above mentioned.
